Transfert register form data to profil fields

Hi @svenl77, thanks for your answer on https://www.ads-software.com/support/topic/transfert-register-form-data-to-profil/#post-9323219 post.

I’m gonna tried to be more clear about my issue.
So I created a regitration form with buddyForm. In this form, the users inputs some data which I would like to copy in the user profil fields without having him to rewrite it once again. Do you know how can I do it? (I’m searching now whats are metadatas). And which files do I need to modify ?

Hope I was clearer,
Thanks for any help,
Thomas
